All Games freezes and crashes!

[Soufiane Attat]

hello friends i have a oem Stock HP Compaq 8000 elite sff with

Q6600 , 6gb ram DDR3 , GTX 750 2GB.

but since i install this GPU on my Computer  all games freezes and crashes randomly  but i can still hear the sound from them until they closes!

i tried everything from uninstalling drivers using DDU to updating nvidia driver,bios,windows 10! but nothing has worked!

i stressed test the GPU with furmark for about 20 minutes with no problems at all ! the temperature never exceed 63c°! please help my guys!

could vga cable or monitor causes this issus? because my monitor screen start flickering and showing some lines randomly long time ago before i even install the gtx 750!!

so i guess the problem isn't with the gpu? help!!
